The Columns and Rows properties get or set the number of columns and rows in which the C1TileViewItem objects are laid out. If the value is zero, it uses the minimum number that does not require scrolling. If both the Columns and Rows properties are set to zero, the items are laid out in a square.

The default state uses the Columns and Rows properties to determine the layout. The minimized and maximized states use the MinimizedItemsPosition property to determine layout. For more information about states, see TileViewItem States.
